Having surprised the boxing world by grabbing Floyd Mayweather from HBO, CBS-owned Showtime will today announce its plan to hype the boxing superstar's Showtime pay-per-view debut May 4 against Robert Guerrero.

CBS/Showtime, including re-airs, will have more than 100 hours of boxing fight replays and new documentary content on Mayweather -- including 20 original hours.

The Mayweather programming will include a prime-time documentary April 3 on Showtime that will detail the boxer's stint in prison last year, a four-part All-Access series starting April 10 as well as a prime-time special on CBS on April 27.

Independent producer Ross Greenburg, a former president of HBO Sports who produced Mayweather documentaries for HBO, will for the first time be involved in Showtime boxing programming.

What Showtime has lined up seems like the type of programming HBO pioneered to hype its fights.

"It should feel a little different than what we did at HBO," Greenburg tells USA TODAY Sports. "But it's still about following the obvious major stories around this fight. And you have a built-in reality TV star in Floyd Mayweather."
